The purpose of this study was to provide evidence of the construct and concurrent validity of the Childhood Career Development Scale’s (CCDS) scores among South African primary school children. Using a sample of 808 children in grades four through seven, evidence for the CCDS’s construct validity was provided using confirmatory factor analysis, with eight factors confirmed. Evidence for the CCDS’s concurrent validity was also presented by analyzing the relationship between subscales of the Childhood Career Development Scale and measures of self-esteem, locus of control, and children’s industry. The CCDS continues to emerge as a promising theoretically-driven assessment tool. 相似文献

This thematic issue of the International Journal for Educational and Vocational Guidance includes a selection of papers presented at the IAEVG-SVP-NCDA Symposium, entitled “Vocational Psychology and Career Guidance Practice: An International Partnership”. The articles in this special issue deal with topics that highlight the interconnection between vocational psychology and career guidance. The authors, because of their different geographical and cultural backgrounds, address these points from their own perspectives. The outcome of the general discussion that centred on these topics at the International Symposium is jointly published in a special issue of the Career Development Quarterly, Vol. 57, No. 4. 相似文献

Research on the impact of professional doctorates on students and their organisations has reported contested outcomes. We undertook a study to develop a causal explanation of how organisational change may, or may not, result from participation in a Doctor of Education programme (EdD). Drawing on critical realist perspectives, the research found that all the doctoral students shared professional concerns with their work colleagues. In some cases, however, this sharing fostered social relations that supported both collective meta-reflexivity and a performative collective reflexivity, and that resulted in organisational change. Variation in the students’ impact on their organisations was further connected to their organisational roles, and to the extent to which their agency aligned with organisational agendas or other external regulatory and normative systems. Strictly limited, or no, organisational change was, however, evident where collective reflexivity was seen to be restricted or to involve contestation. The article concludes that there is significant value to gain by conceiving learning on a professional doctorate not simply in terms of personal growth, but also in terms of mastering a discourse that crosses both research and professional practice and developing the capacity to draw others into that discourse in an organisationally relevant and yet critical fashion. 相似文献

Herein proposed is a simple system to realize hands-free labeling and simultaneous detection of two human cell lines within a microfluidic device. This system was realized by novel covalent immobilization of pH-responsive poly(methacrylic acid) microgels onto the inner glass surface of an assembled polydimethylsiloxane/glass microfluidic channel. Afterwards, selected thiophene labeled monoclonal antibodies, specific for recognition of CD4 antigens on T helper/inducer cells and CD19 antigens on B lymphocytes cell lines, were encapsulated in their active state by the immobilized microgels. When the lymphocytes suspension, containing the two target subpopulations, was flowed through the microchannel, the physiological pH of the cellular suspension induced the release of the labeled antibodies from the microgels and thus the selective cellular staining. The selective pH-triggered staining of the CD4- and CD19-positive cells was investigated in this preliminary experimental study by laser scanning confocal microscopy. This approach represents an interesting and versatile tool to realize cellular staining in a defined module of lab-on-a-chip devices for subsequent detection and counting. 相似文献

A group of seventh- and eighth-grade Italian students with low achievement (LA) in learning English as a foreign language (FL) was selected and compared to a group with high achievement (HA) in FL learning. The two groups were matched for age and nonverbal intelligence. Two experiments were conducted to examine the participants' verbal and nonverbal learning skills, such as native language reading accuracy, speed and comprehension, calculation, and attention and self-regulation. Both experiments showed that the LA group seemed at risk for reading comprehension difficulties, but its reading speed and accuracy were within the average range according to Italian norms. The results also excluded the possibility that FL learning difficulties of LA participants could be associated with a deficit in calculation. Furthermore, according to teachers' ratings, children with LA appeared at risk for attention-deficit disorder (ADD). The pattern of learning difficulties of seventh- and eighth-grade participants with LA appeared to be not completely comparable with that of high school students at risk of FL learning difficulties as described in the literature. 相似文献

Coronavirus disease 2019 (COVID-19) pandemic represents a scientific and social crisis. One of the main unmet needs for coronavirus disease 2019 is its unpredictable clinical course, which can rapidly change in an irreversible outcome. COVID-19 patients can be classified into mild, moderate, and severe. Several haematological parameters, such as platelets, white blood cell total count, lymphocytes, neutrophils, (together with neutrophil-lymphocyte and platelet-lymphocyte ratio), and haemoglobin were described to be associated with COVID-19 infection and severity. The purpose of these review is to describe the current state of the art about complete blood count alterations during COVID-19 infection, and to summarize the crucial role of some haematological parameters during the course of the disease. Decreased platelet, lymphocyte, haemoglobin, eosinophil, and basophil count, increased neutrophil count and neutrophil-lymphocyte and platelet-lymphocyte ratio have been associated with COVID-19 infection and a worse clinical outcome. Our study adds some novelty about the identification of effective biomarkers of progressive disease, and might be helpful for diagnosis, prevention of complications, and effective therapy. 相似文献

57Fe Mössbauer spectroscopy permits an explanation of the formation of the iron-bearing species present in three types of coloured marbles, known as cipollino mandolato, rosso antico and fior di pesco. Structural Fe2+ and Fe3+ located in silicates, together with the remains of weakly ferromagnetic hematite, arise from primary sediments. Fe2+ located in carbonates and anti-ferromagnetic hematite are formed by redox processes during marble formation. The relative contents of the iron species in the three types of marbles depend on the composition of the primary sediments and on local conditions during metamorphism. Knowledge of the type and amount of the iron species in marbles may help in the reconstruction of the redox processes, which took place during marble formation. The deviations of the Morin transition of the hematites play the role of genetic indicator because purity, crystallinity and the red hues of hematites in marbles can be related to the environment of formation. 相似文献
